Specification of Letters Patent.

Patented May 9, 1922.-

Application filed January s, 1921. Serial No. 435,846.

To all whom it may concern:

Be it known that I, WILLIAM M. MURPHY, a citizen of the United States, residing in Glenside, Montgomery County, Pennsylvania, have invented Drink-Mixing Machines, of which the following is a specificatlon.

This invention relates to that class of devices employed for intimately mixing different liquids or one or more liquids with a solid in the preparation of beverages, foods or for other purposes; one object of said invention being to provide a device or machine whereby the materials under treatment shall be so acted on as to insure their intimate and rapid intermingling or mixture. Y

It is further desired to provide a liquid agitating or circulatingdevice with a container of such construction as to insure the movement of the material under treatment in a series of intersecting paths or currents, as well as the breaking up or separation of said currents into smaller bodies with a view to causing a most intimate mixture of the material; the invention contemplating a novel arrangement of bafiie or deflecting plates for accomplishing the aboveobjects.

The invention also includes a novel form of mounting and construction for the bowl of a mixing machine, which will permit of the quick and convenient separation or disassembly of said bowl from the other parts of the device for the purpose of cleaning the same.

structed in accordance with my invention;

and

Fig. 2 is a vertical section on the line 2-2,

Tn the above drawings the bowl or container of the device consists of a cup having a main or body portion 1 of cylindrical form, which at or adjacent its lower end is connected to or formed as part of an an- Another object of my invention is to pro-.

nular, outwardly projecting enlargement,

5 and is designed to screw into the base or stand 3. A plate or washer 6 is engaged by the flange 5 in such manner as to clamp a fiat portlon of the bottom of the container against the fiat upper face of said base.

Rotatably mounted in the sleeve 4 and extending axially of the cup 1 and of its outwardly extending portion 2 is a spindle 7 whose lower end is preferably pointed and extends into a recess 8 concentrically formed in the bottom face of the base 3. This lower end of the spindle has a transversely projecting-pin 9 whose ends are designed to fit into slots in a sleeve fixed to the vertically extending shaft (not shown) connected to a source of power, such as an electric motor,'and the upper end of said spindle has fixed on it within the cup a propeller-like, liquid circulating member 10, in the present instance having two oppositely projecting blades or arms 11. Within the part 2 of the cup the upper end of the spindle 7 is provided with a second laterally projecting pin 12 on which may be removably placed a beater or whipping member for beating eggs or whipping cream within the bowl or cup.

The beating or whipping member in the present instance consists of a spindle 15 having a cavity or hollow at one end for the reception .of the upwardly pro ecting end of the spindle -7, there being twooppositely disposed slots 16 formed in the sides of said end for the reception of the pin 12. Mounted on saidspindle 15 are two annular whipping elements 17 lying in planes at right angles to each other and diametrically engaged by the spindle to which they are rigidly held by any suitable means.

For the purpose of breaking up any rotating currents or masses of material, I provide within thebottom portion 2 of the cup any desired or suitable number of vanes or ribs 13 which are shown in the present instance as extending radially of said bottom portion. In addition I provide a second set of rib 14 projecting inwardly from the side walls of the cylindrical portion of the cup' body, so that under conditions of operation,

the rotation of the member10 through the blades 11 causes the rapid rotation of any liquids or liquids and solids placed within the cup, whose outwardly curved bottom walls cause such liquid to be directed inwardly and upwardly after being forced outwardly by said blades. The inwardly flowing body of liquid thus set in motion by the rotation of the member 10 is forced into and intimately mixed with the downwardly flowing central body of liquid in the cup and while all of said liquid tends to rotate within the cup, this rotation is retarded and the liquid further broken up so that all of its parts are intimately mixed by the action of'the bottom ribs or vanes as well as by that of the inwardly projecting'vanes 14 on the body of the cup or bowl.

When it is desired to use my device for beating or whipping liquids such as cream or the like, the tubular end of the spindle 15 of the whipping attachment is placed over the upwardly projecting end of the spindle 7 to which it is coupled by the pin and slot connection l2l6. Since said spindle when so attached projects axially of the bowl 1, the rotation of the spindle 7 causes its axial rotation and with it causes movement of the heating element 17 in a substantially spherical surface. As a consequence these act on and aerate or finely sub-divide liquid placed within the bowl and this action is materially aided by reason of the other features. of my invention.

As a result of the construction above described,.any liquids or one or more liquids and a solidlor solids are intimately mixed or dissolved one within the other within a minimum of time after their introduction into the bowl. Moreover, when it is desired to clean the latter, access may be had .to all parts of its interior by-unscrewing the sleeve 4 from the base 3, whereupon said sleeve with the rotary member 10 may be taken out of the bowl and after the plate or washer 6 has been removed, all parts of the interiorof said bowl may be readily cleaned or:

scoured. Moreover a similar treatment may be conveniently given to the circulating or agitating element 10 as well of the sleeve 4.

I claim: 1

.1. The combination in a mixing device of a bowl; a base therefor having a threaded opening; a threaded sleeve formed to fit the opening of the base and clamp the bowl thereto; and a liquid propeller rotatably mounted on the sleeve.

2. A bowl for a mixing device consisting of a cup-like container having an outwardly flared, annular bottom portion; with upwardlyprojecting, substantially radial ribs .for the bottom of the bowl.

3. A bowl for a mixing device consisting as to the parts of a cup-like container having an outwardly flared, annular bottom portion; with upwardly projecting, substantially radial ribs for the bottom of thebowl; and ribs extending inwardly from the side walls of said bowl.

4. The combinationof a bowl for a li uid.

mixing device having a body portion, an an outwardly projecting annular bottom por-' tion, said bottom portion lying below the middle line of the bowl and being of lesser height than the body portion; with a liquid impelling device rotatably mounted within the area of said bottom portion.

5. The combination of a bowl for a'liquid mixing device having a body portion and an outwardly projected annular bottom por-- tion; a liquid impelling device rotatably mounted within the bottom portion of said bowl; and ribs projecting into the bowl to intercept rotating bodies of liquid set in motion by the impelling device.

6. The combination in a mixing device of a container having an outwardly flared annular bottom portion; a rotatably mounted liquid impelling device mounted in said bottom portion; and ribs projecting inwardly from. the side walls of the main portion of the container for intercepting bodies of liquid put in rotation by the impelling device.

7 The combination in a mixing device of a container having an outwardly flared, annular bottom portion; a rotatably'mounted liquid. impelling device mounted in said bottom portion; ribs projecting inwardly from the side walls of the main portion of the container-for intercepting bodies of liquid put in rotation'by the impelling device; and other ribs extending upwardly from the bottom portion of .the container.

8. A mixing device consisting of a bowl; a rotatable spindle extending into the bowl through the bottom thereof; a liquid impelling device mounted on said spindle; and a whipping attachment removably mounted on the spindle.

9. The combination ina mixing device of a bowl; a rotatable spindle extending into the same through the bottom thereof; an auxiliary spindle; mean for detachably coupling said auxiliary spindle to said first spindle; and a beating element on the auxiliary spindle.

10. The combination of an open topped bowl; a rotatable spindle extending axially into the same through the bottom thereof;
